On the last day of the school year, mild-mannered high school English teacher Andy Campbell is just trying to keep everything together amidst senior pranks and budget cuts that threaten his job. Unfortunately, things take a turn for the worse when he accidentally crosses his much tougher and hot-headed colleague, history teacher Ron Strickland. After an incident in the classroom results in Strickland being fired, he challenges Campbell to a fist fight after school. Campbell, who is already dealing with chaotic situations at home and work, finds himself desperate for a way to escape the impending confrontation.

As the clock ticks down to the scheduled fight, Campbell embarks on a frantic quest for help from various quirky staff and students, hoping for a solution that will save him from having to face Strickland. During this time, he also has to contend with personal insecurities and spiraling fear as he realizes he might have to actually stand up for himself. The day continues to spiral out of control with humorous and unexpected twists, ultimately leading both teachers to question their actions and what they've been teaching their students by example.
